Credit scores, as with most attempts to make sense of our world, operate on the assumption that the near future will look a lot like the recent past, and that going forward, people can be expected to behave pretty much as they always have.

That is, credit scores base their predictions of the future on their knowledge of the past.

To leverage this knowledge of the past with the idea of building a crystal ball view into the future, the people who build credit scores thoroughly analyze credit bureau information to understand how consumers have gotten to where they are now, and, most importantly, which of the credit bureau data can be used to predict specific future credit behavior for all consumers.

Since most people will exhibit the same behaviors, good or bad, for years at a time, it’s not hard to build a scoring model that simply predicts that people with bad credit today will have bad credit tomorrow, and that people with good credit today will have good credit tomorrow. The trick in credit score building is to predict which consumers with problem histories today are most likely to turn the corner and become low risk — and thus profitable — for lenders in the future, as well as identifying credit applicants who may look good now, but who appear to be headed for financial trouble.

The information used to observe such consumer credit behavior is found in the vast quantities of credit bureau data held by the three major credit bureaus: Equifax, Experian and TransUnion

A key feature of the credit score building process is a “two-snapshot” method of looking at the data. By observing credit reports of a large sample of consumers as of two points in time — the beginning and ending of a two-year period — scoring analysts are able to simulate a laboratory-like study of consumer behavior:

Snapshot 1 — a set of credit reports for a large set of consumers at one point in time, e.g. January 1, 2010Snapshot 2 — another set of credit reports for the same consumers as in Snapshot 1, only two years later, e.g. January 1, 2012

The score developers observe the 2012 credit behaviors for these consumers, such as how they pay and how much they owe, and then take a look back at the 2010 data in search of past behavior patterns leading up to what was seen in 2012. For example, if a high proportion of people who filed for bankruptcyduring that two-year period of 2010-2012 showed late payments on their 2010 reports, while at the same time a high proportion of people who paid all obligations on time during that two-year period had very few late payments as of 2010, it could be concluded that people with late payments today are more likely to file for bankruptcy over the next two years than people with no late payments on their current credit reports.

This kind of information is said to be predictive of future behavior, and is likely to make up the credit scoring factors that become the characteristics of a credit scoring formula. The most predictive of these factors are placed in a “score card” with points assigned for weighting according to their predictive value — with the most predictive characteristics assigned the most possible points. The sum of all points achieved for these factors becomes the credit score representing the risk for a particular consumer.

With the benefit of hindsight, it is now commonly known that consumers pose lower future credit risk when they:

Make all payments on timeKeep credit card balances lowHave many years of credit experienceOpen new accounts only occasionallyHave a good mix of credit experience

Sound familiar? It should, as these results come from many years of research into the predictive value of credit bureau data, and not only remind us that people who demonstrate positive credit management practices at the beginning of any time period are most likely to be demonstrating these same attributes later on, but also that many consumers deviate from their past behavior — either in good or bad directions — and that for lenders the ability to identify these consumers is where the money is.

The economic recovery is certainly in full swing and has been for some time now. That, coupled with better habits related to handling debts of all kinds, has led millions of consumers to see significant improvements in their finances over the last few years.

Household debt of all kinds slipped some $110 billion in the first three months of the new year alone, bringing total nationwide obligations to just $11.23 trillion, down appreciably from the all-time high of $12.68 trillion observed in the third quarter of 2008.

Here are seven signs that household finances got stronger in the first quarter of the year, based on data from the latest Household Debt and Credit Report issued by the Federal Reserve Bank of New York.

Only two types of debt — student and auto loans — actually increased during the first quarter of the year, as the former rose another $20 billion to a total of $986 billion nationwide, continuing a trend seen over the last several years. The latter, meanwhile, ticked up $11 billion to $794 billion during that time.Home equity lines of credit slipped $11 billion to just $552 billion.Mortgage debt fell $7.93 billion to $8.03 trillionNew foreclosure notifications slipped 12.5 percent from the previous quarter to just 184,000 households nationwide, marking the fourth straight three-month period in which there has been a decline in this area.The drop in mortgage debts came even as lenders issued $577 billion in new mortgage credit thanks to the sixth straight quarter of increases in new originations.Credit card balances slipped some $19 billion from January to March, bringing the national total owed on these accounts to just $660 billion.Significantly late payments on every type of credit listed above dropped, bringing the national 90-day delinquency rate to just 6 percent of all balances, down from 6.3 percent the previous quarter and 8.7 percent at the all-time high in the same period three years earlier.

Experts have long speculated that rates of delinquency and default must logically bottom out at some point in the near future, but consumers keep defying those expectations.

Many borrowers changed their habits as it relates to debt in general as a result of the financial difficulties they faced during and even following the recent recession, during which time default rates skyrocketed and led to consumers having bad credit and other significant financial difficulties.
